Cisco VWIC-1MFT-E1

These flexible interface cards support multiple integrated data, voice and video applications, facilitating the
migration from data only as well as circuit-switched voice/video services to a packet voice/video solution

Introduction

The Cisco® Third-generation 1-, 2-port and 4-port T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC3s) support
data and voice applications on the Cisco 1921, 1941 and 1941W (data only), and the Cisco 2901, 2911, 2921, 2951,
3925, 3945, 3925E and 3945E Integrated Services Routers. The Cisco MFT VWIC3 combines WAN-interface-card
(WIC) and voice-interface-card (VIC) functions to provide unparalleled flexibility, versatility, and investment
protection through its many uses. Customers who choose to integrate data and voice in multiple steps preserve their
investment in a T1/E1 WAN interface because the Cisco MFT VWIC3 cards can be reused in packet voice
applications.
